Answer: Hello dear many congratulations for pregnancy
An AFI between 8-18 is considered normal. Median AFI level is approximately 14 from week 20 to week 35, when the amniotic fluid begins to reduce in preparation for birth. An AFI < 5-6 is considered as oligohydramnios. The exact number can vary by gestational age.
As the baby grows it produces more amniotic fluid. The amount increases until the baby is about 32 weeks gestation. The amniotic fluid levels then remains constant until the baby is full term (37 to 42 weeks) when the levels start to decline.
Healofy wishes you all the very best

Answer: Hi
Amniotic fluid index(AFI),should be at any stage during pregnancy is between 10- 18. Ideally 12 is good. But your level is 19 its high,its not possible to do normal delivery because the high AFI could make the normal delivery difficult and you could deliver through c section .also low AFI could give you preterm delivery. Risks: 1- baby could not develop lungs and muscles well.as from second trimester,baby starts to swallow the fluid and recycle it 2- increased chance of miscarriage or still birth.
